I'm a little surprised to see a number of anti-immigraiton comments on this thread, some of which you could describe as reactionary.
The US is and always has been a country of immigrants. Your idea of who is and isn't an immigrant is simply a question of what time window you choose. In 1800, the US had a population of ~2 million. by 1900 it was ~50 million. You want to guess how itt got that way?
Let's dispense of the common issues:
1. Tech layoffs. This is unrelated to immigration. This is de facto employer colusion to suppress wages. Notice how all the tech companies started doing layoffs at about the same time? The counterargument is "economic conditions". You may have a point with VC funding drying up due to rising interest rates but many of the biggest companies are massively profitable. Profits tend to fall so they want to suppress costs to maintain profits. That's it.
I will say that layoffs should basically prohibit you from applying for more work visas for a period. For example: if you've laid off anyone in the last year, sorry you can't sponsor a work visa. You can escape this by, say, paying severance of at least a year's total compensation. The point is to remove the economic incentive of suppressing wages from the layoff-then-rehire cycle.
2. Lowering wages. Restricted immigration actually lowers wages. Why? Because it allows employs to pay undocumented workers less. Poultry farms are an excellent example of this. They pay undocuemnted workers less. If they ever start making noise about wages or conditions, you clear them out by calling in an ICE raid, pay a nominal fine, rinse and repeat.
How do we know this? Because when states actually go after employers rather than the workers, it's an economic disaster [1].
Also, we used to have a temporary worker program for seasonal and agricultural workers called the Bracero program. This filled an economic need. Eliminating it created more undocumented residents because crossing the border became too difficult and expensive.
3. A rising tide lifts all boats. There's mountains of evidence for this (eg [1]). Unions increase non-union wages. If we didn't have wage suppression by forced undocumented workers it would raise wages for everyone.
Immigrants aren't "stealing your jobs" or "lowering your wages". There's a long history of trying to blame immigrants instead of (correctly) blaming the concerted effort by capital owners to lower your wages.
